E36 PWR 42mm Aluminum Radiator Upgrade - (NO LONGER AVAILABLE)

The 42mm PWR Euro E36 radiator fits the Euro E36 M3 models as well as US-spec E36 325, 328, and M3s. This radiator has a core that is 4mm larger than the stock Behr radiator. If you're looking for a radiator with more cooling capacity and a provision for the stock Euro oil cooler, this is the one. Everyone knows the E36 has an Achilles heal in the cooling system with flimsy radiator necks, plastic materials, unreliable water pumps, and not a lot of capacity for some applications. PWR has addressed some of these issues with a slightly thicker radiator, able to hold more fluid. Increasing the amount of fluid in the system leads to shorter saturation times (the length of time the cooling fluid is exposed to engine heat) which will give you more consistent engine temperatures, reducing wear and tear on other cooling components such as the water pump and thermostat. This is great as a durable replacement radiator for a street car or as an upgrade for a track car. For super-serious cooling capacity check out our PWR 55mm radiator, however, if you don't need the additional capacity we recommend the 42mm unit because of its lighter weight (both in the radiator itself and carrying less fluid).

Not only is this radiator larger, it's designed with the stresses of motorsports in mind. The cooling vanes use a unique oven-brazed bonding technology that will not fatigue and crack like epoxyed construction. We have been more impressed with the fitment and quality of PWR over any other brand currently on the market. Aircraft-grade aluminum is used for the tanks and frame, which are TIG-welded for superior strength. We like this radiator a lot for dual-purpose track/street cars because it does not intrude too much into the engine bay and it's a direct fit with the factory Euro oil cooler and factory mounting hanger (note: not TMS oil cooler hardware). The factory Euro oil cooler hanger will have to be used if you're using the factory oil cooler (we sell the hanger alone if you need it). That makes this radiator a plug-in upgrade for true Euro-spec cars. With or without an oil cooler, this radiator is a direct replacement for the stock E36 radiator, with all of the same hose locations and fittings as the original radiator. It mounts to the car with the original clips on the radiator support and the fan shroud/expansion tank bolts to the radiator (you will need to supply your own M6 and M8 hardware as spacing and installing the shroud can be done several different ways). Each radiator is pressure-tested during manufacturing.

PWR is a world-renowned radiator manufacturer, supplying all forms of motorsport from Formula One (2010 World Champion Sebastian Vettel) to WRC to NASCAR. Our TMS Race Team uses PWR for our cooling needs in the Rolex GT and Continental Sports Car series.
